Reno A&E AX-8 Single Channel Loop Detector, 240VAC
The AX-8 is a single-channel detector designed for systems that power the detector from a 240VAC source. It reads one inductive loop and provides a relay output to the connected gate operator or access controller when a vehicle is present. In the field, this detector may be found in older commercial gate panels, parking lane controls, barrier gate systems, and access-control cabinets where a simple one-output detector was specified. The AX Series uses DIP switches instead of a digital display, so the replacement must be set to the proper sensitivity, frequency, presence or pulse behavior, and delay settings after installation. The biggest ordering risk is voltage: an AX-8 is not a replacement for an AX-4 low-voltage unit or an AX-3 120VAC unit.
Compatible With
This detector may be used with the following applications when the original voltage, connector style, output logic, and control-board documentation match:
- Older Reno A&E AX-8 240VAC detector installations.
- Select gate operators, parking controllers, traffic/access panels, and barrier controls using compatible 240VAC detector power.
- Applications requiring one loop channel and one relay output.
- Exit loops, safety loops, vehicle presence loops, and access-control call loops when wired to the proper input.
- Related replacement/search references include AX-8, AX8, AX-8-S, BX-8, BX8, SKT-11, and 802-4 when voltage and output requirements are confirmed.

Technician Note
Loop detector problems are not always caused by the detector module. A damaged loop, wet splice, poor lead-in cable, wrong sensitivity setting, frequency interference, or a loop installed too close to moving gate steel can create false detection or missed vehicles. Match the detector first, then test the loop and operator input before returning the gate to service.
Before Ordering
- Match the detector input power to the original unit and operator control voltage: 240VAC AX Series model.
- Verify the connector style and pin layout before ordering: 11-pin detector socket style - verify original installation.
- Confirm the required output style for the operator input: Single relay output.
- Check whether the original application uses presence, pulse-on-entry, pulse-on-exit, fail output, or safety/hold-open logic.
- Inspect loop wire, lead-in cable, splices, and pavement cuts before assuming the detector module is the only failed part.
Important Ordering Warnings
- Do not interchange 120VAC, 240VAC, and low-voltage detector models by appearance alone.
- Do not assume fail-safe and fail-secure versions are interchangeable.
- Confirm 11-pin socket detectors versus plug-in Molex style detectors before ordering.
- Check whether the application needs relay outputs or solid-state outputs.
Professional Advisory
Do not use a loop detector as a replacement for required monitored photo eyes, safety edges, or entrapment protection devices. For high-voltage detector power, damaged wiring, nuisance gate movement, or uncertain safety-device wiring, have the system checked by a qualified gate technician.
Product Questions and Answers
Is the AX-8 the 240VAC detector?
Yes. The AX-8 is the AX Series model for 240VAC detector power and should not be installed in 120VAC or low-voltage detector sockets.
What is the common newer replacement for an AX-8?
The BX-8 is commonly referenced as the newer 240VAC BX Series replacement path, but wiring and output needs should be confirmed before substitution.
Can this detector be used on a safety loop?
It can be used for a safety or hold-open loop only when the connected operator input is wired and configured for that function.
Why does voltage matter on this detector?
Applying the wrong voltage can damage the detector and may create an unsafe or unreliable gate control condition.
Does the AX-8 include a socket base?
Detector modules are commonly sold as the plug-in detector only. Confirm whether a socket base or harness is needed for the job.
